How long do smoothing treatments last?

All of our smoothing treatments — including Brazilian Blowout, Cezanne, and Keratin Revolution — last up to 12 weeks with proper care. The QiQi Curly Treatment is different: it's permanent until cut out, since it reshapes the internal bonds of the hair rather than coating or sealing them.

When should I color my hair in relation to a smoothing treatment?

Single-process color can be done before any smoothing treatment, or two weeks after for Brazilian Blowout, Cezanne, or Keratin Revolution. With QiQi, you can color, swim, and style before or after your treatment — there are no restrictions, except one: if you're lightening with bleach, that must be done before the treatment. Toners can be applied anytime afterward to refine brightness or tone if your color shifts slightly. We'll help you plan your color and smoothing schedule so everything stays even, glossy, and healthy.

Will a smoothing treatment change my hair color?

Most smoothing systems can slightly lighten single-process color and may warm or yellow gray and white hair, especially with heat. The QiQi Curly Treatment is the exception — it does not cause color shift and is ideal for clients with lighter tones or gray hair who want smoothness without fading.

Will smoothing make my hair flat or take away volume?

Not unless you want it to. Every service is customized to your texture and preferences — from soft, frizz-free curls to smooth, max results. Our goal is always healthy movement, not heavy or lifeless hair.

Can I swim? Do sulfates, salt water, or chlorine affect smoothing results?

Yes — sulfates, salt water, and chlorine all speed up the fading process. They strip the protective layer that keeps hair smooth and shiny, shortening the life of your treatment. QiQi – Keep All the CURL is our only treatment that allows you to swim immediately after receiving it.

What if my hair is damaged?

If your hair is compromised or overprocessed, we'll still take great care of it — we'll just approach things a little differently. Delicate or fragile areas will be treated with lower heat and a gentler technique, which means your first result may be less dramatic than usual. The goal is to protect your hair's integrity first, then build it back up over time. We can create a restoration plan that combines targeted treatments, proper at-home care, and gradual smoothing so your hair gets healthier with every visit. Once your strands are stronger, we'll be able to perform the treatment at full strength for a more transformative and lasting result.

Can I do a smoothing treatment if I use henna or minoxidil?

No — smoothing treatments cannot be done over henna or on hair being treated with minoxidil. These ingredients can react unpredictably with smoothing systems. We'll help you plan a safe timeline if you've used either recently.

Are these straightening treatments?

No — none of these are straightening treatments. They're smoothing systems, which means they reduce frizz, add shine, and improve manageability while keeping natural movement. Because these treatments don't break and reform bonds like relaxers, we can't guarantee completely straight hair for every texture — but we can guarantee smoother, healthier, humidity-resistant hair that behaves beautifully in Boston's weather. If your hair is frizzy-straight or has a loose wave, it will appear smoother and straighter. If your hair is curly or coily, you'll still have curl and bounce — just softer, shinier, and easier to style. All of our treatments have a cumulative effect and will build on the hair with regular treatments.

What's the difference between the treatments you offer?

Each treatment uses its own science and active ingredients: Brazilian Blowout coats the hair for high-gloss, frizz-free smoothness. Cezanne gently rebuilds and refines the cuticle with a formaldehyde-free formula. Keratin Revolution combines keratin and glycolic acid for stronger smoothing and shine. Results are a little stronger than Cezanne. Formaldehyde-free. QiQi Keep All the CURL permanently reshapes curls for softer, defined texture without losing bounce. Formaldehyde-free. During your phone consultation, we'll help you choose the perfect system based on your hair and goals.

Why choose Brazilian Blowout Boston?

Because smoothing isn't a side service here — it's our specialty. We're the only salon in Boston fully dedicated to professional smoothing systems. Every stylist is trained in product science, safety, and precise application to deliver consistent, glossy, frizz-free results. Clients travel from NY, RI, NJ, CA, CT, VT, MN, LV, Cape Cod, Quincy, Milton, South End, and beyond because they know they'll leave with hair that's glossier, healthier, and easier to manage — every single time.

Brazilian Blowout Aftercare in Boston: Wash Day and Beyond

September 25, 2026

You can wash your hair the same day you leave a Brazilian Blowout appointment. No three-day wait. No dry shampoo marathon, no sleeping sitting up to protect a result you just paid for. That one fact confuses more new clients than anything else about this treatment, mostly because somebody's friend booked a different smoothing service somewhere else and passed along rules that were never ours.

We have done this over 10,000 times since 2016 out of our studio at Marina Bay in Quincy. Nearly every aftercare question we get traces back to someone comparing this treatment to a different one. So here is the honest version. What holds a Brazilian Blowout together, what wears it down, and what your hair looks like at week six versus week eleven.

Can You Wash Your Hair the Same Day?

Yes. You can shampoo the same day you walk out of the studio. Brazilian Blowout does not carry a three-day no-wash rule. Many older keratin formulas do, and that is where the confusion starts. Wash on your normal schedule, beginning the day of your appointment. What matters far more for how long the smoothing holds is which shampoo you reach for.

The reason this gets muddled is that "keratin treatment" has turned into an umbrella term. Hundreds of different formulas sit underneath it, and they do not follow the same rules. Brazilian Blowout is a brand with its own chemistry and its own process. Same-day washing is one of the first things we cover on your complimentary 10 to 15-minute phone consultation, before you ever book a chair.

We only do this one treatment. No cuts, no color, no other chemical services. That focus is a big part of how we keep the rules straight for every client who sits down, instead of guessing at aftercare for six different smoothing systems.

A quick shower the same night, air drying, a normal wash the next morning: all fine. Nothing about the first 72 hours is fragile.

What Changes After Your Appointment

Your hair does not leave here in one standard finish. We build every treatment around your texture, curl pattern, strength of curl, condition, and chemical history, and we work in three result levels: Classic, Lighter, and Heavier. A client with thick, resistant curl who wants a fuller smoothing effect gets a different plan than a client with fine, highlighted hair who needs a more conservative approach to protect color and strength.

Fine, highlighted, or chemically processed hair gets a lower temperature and a lighter hand during the treatment itself. That is not a watered-down version of the service. It is the correct version for that hair. If you color and want the sequencing spelled out, our page on protecting color and strength through smoothing walks through the order we recommend.

Appointments run 90 minutes to five hours depending on length and density. The studio is private and fully ventilated, with fans running, which is the only reason a five-hour smoothing appointment is comfortable to sit through. Clients who have had this done in a crowded salon usually notice the difference in the first ten minutes.

We also ask that hair arrive reasonably clean, without heavy oils or product buildup. Not required. We clarify in the studio regardless. It just gives us a clearer read on your natural texture before we lock in a result level.

Everything from your consultation and your appointment goes into your file. The first treatment is a jumping-off point, not a permanent formula. If something about the result surprises you, that feedback becomes part of your notes and shapes the adjustment next time.

Why Your Shampoo Decides How Long It Holds

After 10,000-plus treatments, the single clearest pattern we see is this: the clients who go back to a stripping detergent shampoo lose weeks off their result, and the clients who switch to sulfate-free hold on to it.

Here is the mechanism in plain terms. A Brazilian Blowout works by sealing an amino acid layer around the outside of each strand with heat. That layer is what flattens frizz and cuts your blow-dry time. A harsh, high-foam detergent is built to lift oil and residue off the hair surface, and it does not distinguish between buildup and the smoothing layer sitting on top of your cuticle. Wash after wash, it wears that layer thinner. Nothing dramatic happens on day one. You just find yourself at week seven with hair that behaves the way it did at week eleven last time.

Wash frequency stacks on top of that. Someone shampooing daily is running through more cycles than someone washing twice a week, so the same product choice plays out faster. If you work out most days, rinse and condition rather than lathering up every single time.

Chemical services in between matter too. A client who colors frequently between visits tends to see the smoothing soften a little sooner. That is one more reason we ask about your color plans on the consultation call and not after your appointment.

Heat, Chlorine, and Humidity Through the Full Window

The treatment is heat-sealed, so heat styling afterward is not the enemy people expect. You can flat iron. You can blow dry. Most clients find they barely need to, which is the whole point.

What we would rather you avoid is high heat on dry hair repeatedly with no protectant, day after day, on the same sections. Fine and previously highlighted hair is where that shows up first, usually at the mid-lengths. Use a heat protectant, keep the iron moving, and one pass is plenty on smoothed hair.

Water exposure is the one worth planning around. Chlorinated pools and salt water are both drying, and both will pull at a smoothing result faster than your shower does. Two things help. Saturate your hair with fresh water before you get in, so it absorbs less of the pool, and rinse and condition as soon as you are out. Ocean days on the South Shore are the same deal. Rinse before you drive home, not after it dries in.

Humidity is the reason most people in Quincy book this in the first place. Coastal air holds moisture that pushes into a raised cuticle and swells it, which is what frizz is. A fresh treatment resists that because the cuticle is laid flat and sealed. As the result softens, humidity gets its grip back gradually, and it does not happen evenly across your head. If you want the longer version of that, we go deeper in our guide on beating Boston summer humidity and in our piece on coastal frizz from salt air.

What Week Six Looks Like Versus Week Eleven

At week six, most clients cannot tell much has changed. Hair still air dries close to smooth. A humid morning might raise a little texture at the crown that brushes out.

By week eleven, the pattern is different. Frizz comes back first at the hairline and the nape, because those are the shortest, finest, most exposed hairs on your head. Your blow-dry starts taking a few minutes longer. The ends still feel smooth while the roots have opinions again. That uneven return is normal, and it is the honest signal that you are near the end of the window rather than a sign something went wrong.

Most clients start thinking about rebooking around week ten. Booking before the softening becomes obvious keeps your hair looking finished more of the time.

Original Brazilian Blowout Versus the Formaldehyde-Free Option

We offer both. The right one depends on your situation, not on which one sounds stronger.

	Who it suits	Result to expect	Aftercare
Original Brazilian Blowout	Most clients wanting the fullest smoothing effect	Closest to a fully smoothed, frizz-free finish	Same-day washing, sulfate-free products
Formaldehyde-free option	Clients who are pregnant, breastfeeding, or who prefer to avoid that exposure	A real smoothing effect, not necessarily identical to the Original	Same-day washing, sulfate-free products

We do not perform the Original treatment on clients who are pregnant or breastfeeding. The formaldehyde-free option exists for exactly that situation, and we are direct on the consultation call that it may not deliver the same result as the Original. How long either one holds depends on your hair, your wash routine, and what we are asking the treatment to do. Setting that expectation up front beats a client leaving disappointed because a friend's Original set the bar.

Both are washed and cared for the same way afterward. Sulfate-free products, normal life, no waiting period.

What Clients Get Wrong About Aftercare

The most common mistake is assuming Brazilian Blowout aftercare matches whatever a friend was told after a different smoothing service. It usually does not. We meet clients who are still avoiding water for three days out of pure habit from a treatment they had years ago somewhere else.

The second is going straight back to the same drugstore shampoo out of convenience. It feels like a small shortcut. It is the fastest way to shave weeks off a result meant to carry you into the third month.

The third is drying the hair aggressively with a towel. Rough terry cloth lifts the cuticle mechanically, which undoes some of what the heat seal did. Squeeze, do not scrub.

And the fourth is skipping the phone consultation and assuming every Brazilian Blowout behaves the same. A treatment built for fine, highlighted hair looks and lasts differently than one built for thick, resistant curl. Going in without that call is how expectations get mismatched before a single strand is touched. If you have not had that conversation yet, book your consultation first.

Your First Two Weeks, Step by Step

Wash whenever you normally wash. Same day, next morning, either is fine. There is no waiting period built into this formula.
Switch to a sulfate-free shampoo and conditioner. This one change does more for longevity than everything else on this list combined.
Squeeze water out, do not scrub it out. A soft towel or a cotton t-shirt, pressed, not rubbed.
Live in your hair normally. Ponytails, clips, hats, workouts, all fine. There is no pressure restriction with this treatment.
Use a heat protectant if you are ironing. You probably will not need the iron much, and when you do, one pass is enough.
Rinse with fresh water before and after swimming. Pool or ocean, same rule.
Flag anything unexpected. If one section feels rougher than the rest, tell us. That detail goes in your file and changes the plan next time.

Done right, none of this feels like a routine you have to think about. That is the point of choosing a treatment that never came with a waiting period.

What the Result Looks Like

Words only go so far. One client, a mother of three, put it this way on Google: "For the first time in my life, I can let my hair air dry and it's straight and shiny, just as I always wanted!" That is the finish we are aiming at on the first wash, not eventually.

You can see more of that on our before and after Brazilian Blowout results page. If you are weighing this against a keratin smoothing service, our keratin smoothing treatment page lays out the difference. And once your hair settles into its new rhythm, most clients start air drying more often instead of blow drying every strand, which is covered in our guide to air-drying curly hair without humidity frizz. If cutting styling time is your main reason for booking, this piece on styling time for wavy hair is the honest math.

Pricing depends on your hair length, density, and the result level we settle on. We go through it on the phone consultation so there are no surprises when you arrive.

Frequently Asked Questions

Do I really not have to wait three days to wash my hair after a Brazilian Blowout? Correct. You can shampoo the same day you leave the studio. That is one of the clearest differences between this treatment and older keratin smoothing formulas that do build in a waiting period.

How long do most Brazilian Blowouts last? Most clients get roughly ten weeks to three months out of a treatment. How close you get to the far end depends mostly on how often you wash and whether you switched to sulfate-free products.

Does hair go back to normal after a Brazilian Blowout? Yes. This is a temporary smoothing treatment, not a permanent chemical change to your curl. Your natural texture returns gradually as the smoothing layer softens, starting at the hairline and nape.

Do they wash your hair before a Brazilian Blowout? We clarify the hair in the studio before every treatment, no matter how it arrives. Clean, dry hair without heavy oils or product buildup is ideal, but it is not a requirement to book.

Is a Brazilian Blowout the same as a keratin treatment? No. Brazilian Blowout is a specific brand with its own formula and its own rules. "Keratin treatment" is an umbrella term covering hundreds of different products, which is exactly why aftercare advice from one does not transfer to another.

Which is better, keratin treatment or Brazilian Blowout? It depends on the result you want and what your consultation uncovers about your hair. We only perform Brazilian Blowout here, and we will tell you plainly on the call if we do not think it fits what you are after.

Can I swim with a Brazilian Blowout? Yes, with two small habits. Wet your hair with fresh water before you get in, so it absorbs less pool or salt water, then rinse and condition as soon as you are out.

What are the potential downsides of a Brazilian Blowout? The biggest one is mismatched expectations, usually from comparing it to a different smoothing service a friend had. Skipping the phone consultation and going back to a stripping shampoo are the two things most likely to cut your result short.
